I am a big fan of Bitshare too. I think Dan Larimer an honest young man with lots of integrity and obviously he is an extra clever guy. As far as I know GadgetCoin uses the Bitshare methodology to pedge the token to 1US$ though I am not entirely sure if that is really the case.
I hope they will work with Bitshare, both projects could gain a lot from a partnership.

I also suggested already to these guys to try working with Supernet as well. I always have a mixed feelings about James (jl777) but one thing is sure he knows what he is doing and he is an extra talented guy, again both projects could gain from the partnership.
